When we talk about dust, we think, primarily, of house dust or particulate matter which are included as a particle in the air. The biggest portion in dust production comes from the industry. The lion‘s share of dust emissions originates from grinding, conveying, casting, transporting, drying, mixing. Environment protection laws and dust removal plants exist to prevent this. Such installations are built for over 90 years by the Velbert placed company Intensiv-Filter and are in use on all continents.

The list of dusts is long and ranges from explosive, toxic and carcinogenic solids to metals and pharmaceutical active substances. If the dust deflates from the stack, it is a danger for person, environment, machines and facilities. To prevent this environment protection laws and filtering installations exist.

Such filters are used to reduce dust issues with the cement production, by the steel processing, in the chemical industry or also in the production process of milk powder. There is almost no branch or procedure-technical process in which dust removal solutions of Intensiv-Filter from Langenberg are established.

The company took its beginnings with the company founder Theodor Hansen from Wuppertal who developed 1922 first filters for the mining industry. In 1930 his company moved to the area at the railway station in Langenberg. The demands for filtering installations became more and more differentiated with so many different production processes and dust removal products. There are filter though also from the pole, however, must be tailored in many cases especially for the planned duties. The strictest demands for hygiene in the food industry require, for example, other equipment than the construction of the cement industry in the Ukraine which became a premise for the construction of the football stadiums for the European championship.

Growing environmental standards all over the world allow to expect that still a high order potential slumbers in the dust removal of industrial processes. An important reason to stick in spite of temporary insolvency to the participation at the worldwide biggest trade fair for chemical process technology „Achema" in Frankfurt.

While on the one hand the insolvency trustee must protect the economic existence of the traditional company, the exhibition stand of Intensiv-Filter has been much frequented at the Achema. Also the development in the world economy is a guarantee for growth of the company: Thus the productions, which do not get by without filters, are built up above all in threshold countries like India or Brazil. China has a high potential due to its growing industrialisation. „In Mongolia e.g the environmental conditions are characterized by considerable air pollution. It is therefore necessary to deal more and more detailed with the reduction of industrial dust emissions and an improvement of the air quality," says head of marketing Astrid Kögel.

With so much relevance of the traditional company from Langenberg, the present insolvency proceedings also have an important political dimension. „We wish the insolvency trustee a hot hand", says Member of the NRW Parliament Volker Münchow. „Intensiv-Filter is a distinctive mark for creativity and international standing of the medium-sized economy in the Bergisch region ."
